Abstract

A radiation sensitive composition comprising (1) a phosphor; (2) an organic polymer binder comprising a combination of at least one alkali-soluble resin and at least one cellulose ether; (3) a photo-crosslinkable compound; and (4) a photo-radical generating agent.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A radiation sensitive composition comprising: (1) a phosphor;   (2) an organic polymer binder comprising a combination of at least one alkali-soluble resin and at least one cellulose ether;   (3) a photo-crosslinkable compound; and   (4) a photo-radical generating agent,   wherein said cellulose ether is selected from the group consisting of 2-hydroxypropyl cellulose, 2-hydroxyethyl.methyl cellulose and 2-hydroxypropyl.methyl cellulose.   
     
     
       2. The radiation sensitive composition of claim 1, wherein the alkali-soluble resin is selected from the group consisting of (meth)acrylic resins, hydroxystyrene resins and novolak resins. 
     
     
       3. The radiation sensitive composition of claim 1, wherein the alkali-soluble resin is a copolymer containing 10 to 90 wt % of an alkali-soluble monomer as a copolymerizable component. 
     
     
       4. The radiation sensitive composition of claim 1, wherein the organic polymer binder comprises an alkali-soluble resin and cellulose ether in a weight ratio of 10:1 to 10:30. 
     
     
       5. The radiation sensitive composition of claim 1, wherein the photo-crosslinkable compound is a polyvalent (meth)acrylate of a polyvalent hydroxy compound. 
     
     
       6. The radiation sensitive composition of claim 1 which comprises 10 to 2,000 parts by weight of the phosphor based on 100 parts by weight of the organic polymer binder. 
     
     
       7. The radiation sensitive composition of claim 1 which comprises 5 to 500 parts by weight of the photo-crosslinkable compound based on 100 parts by weight of the organic polymer binder. 
     
     
       8. The radiation sensitive composition of claim 1 which comprises 5 to 500 parts by weight of the photo-radical generating agent based on 100 parts by weight of the photo-crosslinkable compound. 
     
     
       9. The radiation sensitive composition of claim 1 which further comprises a solvent.
